MOTOR-CAR.

SPECIFICATION forming part of Letters Patent No. 379,119, dated March 6, 1888.

Application filed July 16, 1887. Serial No. 244,491. (No model.

To all whom it may concern:

Be it known that I, PATRICK J. ll/IOMAHON, a citizen of the United States, residing at New Orleans, in the parish of Orleans, State of Louisiana, have invented certain new and useful Improvements in Motor-Oars, of which the following isa specification, reference being had therein to the accompanying drawings.

This invention has relation to a motor-car designed for the transportation of passenger, street, and other cars, and for the reception, utilization, and operation of an ammoniacalgas engine or motor and a generator for th same. I

The general object of the invention is to construct a passenger-car (which may be also used as a motor-car by which other passengercars may be propelled) in such manner as to carry a generator and motor of the class above mentioned without affecting the convenience, strength, and serviceability of the car as a passenger-car.

Another object of the invention is to con nectthe motor with the car in such a manner that the latter may run at will, either at ahigh speed or low speed, and with greater power, as when ascending grades or heavily loaded, or in such manner that the car may be run independently of the motor, as by momentum resulting from speed given by the motor or when running down grades.

Other objects and advantages of the'invention will hereinafter appear, and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a side elevation of a street-car provided witha motor of the class described and constructed in accordance with my invention. Fig. 2 is a vertical transverse section on the line 00 a: of Fig. 1. Fig. 3 is a plan of the gearing employed for connecting the motor with the car.

Like letters of reference indicate like parts in all the figures of the drawings.

The particular ammoniacal-gas generator herein shown is not herein claimed, as it forms the subject-matter of another pending application, filed July 16, 1887, Serial N 0. 244,492.

The frame-work A of the car may be of any usual desired construction, and the wheels and axles may be also connected to the frame-work in any ordinary well-known manner. In this instance I have arranged seats B for the passengers longitudinally and centrally in the car and have provided the usual platforms, B, along the sides ofthecar. Suitable standards, 0, serve to support the .roof D. A dash or end wall, E, is provided at one or both ends of the car, as desired.

I utilize the space under the seats for the generator F F, the latter part being the cylinder having the'flues or pipes F and arranged within the tank F, and which, by means of the pipe G, is adapted to receive the exhaust from the motor H, the supply of ammoniacal gas to the motor being conducted by the pipe I, hav ing the valve or cook I to control its admission into the motor, which pipe communicates with a gas-drum, J, arranged overhead in the car and-connected with the supply-tank F by a pipe, 1 The object of arranging the gasdrum overhead is to insure dry gas for sup plying the motor.

Asiphon, K, extends from the tank F into the air-trap K, having the outlet K. (See Fig. 1.) A stop-cock or valve, F (see Fig. 1,) affords one means for charging the tank F,

and a pipe, F, is provided for filling or discharging the cylinder F.

The motor H, as shown, is arranged upon one end of the car, and is connected to the axle of the car by the following mechanism: Upon the axle L is a large gear, L, and a small gear, I

M are the brackets, which depend from the frame-work of the car and serve as journal-bearings for a counter-shaft, M, on which is a small gear, M arranged to mesh with the large gear L of the axle, and alarge gear, M arranged to mesh with the small gear L of the axle. Upon the counter-shaft M is a sliding clutch-sleeve, N, having clutches or arms N projecting therefrom, and adapted to take against the projecting lugs O, arranged upon the inner sides of the gears M M. A lever, P, pivoted, as at P, to theframe-work or bottom of the ear,embraces the sleeve M and rides in a groove, P formed therein, so that the sleeve may be rotated and yet be reciprocated upon the shaft by the lever P. A sprocketwheel, Q, is rigidly mounted upon the sleeve, so that the latter can, by means-of a sprocketchain, Q, properly connected with the crankshaft of the motor,be rotated. Now, it will be seen that by means of the lever P the sleeve N may be reciprocated, so that the motion of the sleeve will be given to the small gear M which isloosely mounted on the counter shaft, so as to drive the axle and propel the car, through the medium of the large gear L, the speed being slow and the power comparatively great. It will also be seen that by partly reciprocating the sleeve,so as to throw the clutelr arms into contact with the lugs O of the gear M which is loosely mounted on the countersha-ft, the rotation of the clutch will be given to the axle L and the car propelled by means of the gears M L", the speed being greater than when the power is conveyed through the other end of the sleeve, as above described. Again,it will be seen that by sliding the sleeve by means of the lever F, so that neither end of the same is in connection with either gear of the countershaft, the car may be run by momentum and without the use of the motor. The lever P is pivotally connected with the hand-lever R near the motor, so that various dispositions of the sleeve can be accomplished by a single attendant.

It is only necessary to state in regard to the particular generator herein described that liquid ammonia is placed within the tank F, and a reabsorbing liquid within the cylinder F, so that by means of the pipes and connections, hereinbefore described, the latent heat, made manifest or sensitive by the condensation of the exhaust and its reabsorption within the cylinder F, is given off and transmitted through the body of the cylinder to the am monia within the tank, so that the ammonia is evaporated to a gaseous form and rises to the gas-drum J, and is conducted thence to the motor under pressure and utilized as the power-giving agent of the motor.

Any air accumulating within the tank F passes up the siphon K and over into the airtrap K, which is partly filled with water. The water absorbs any ammoniacal gas commingled with the air, while the air passes upwardly through the pipe K to the external atmosphere, and any odors carried by said air are diffused above the heads of the occupants of the car and therefore become unobnoxions.

I deem it proper to state that my present invention is not limited in any regard, so far as the particular form of generator or motor is concerned; and, furthermore, as is ap parent, the generator need not extend the entire length of the car and may be located under the seats when the same are arranged crosswise of the car. So, also, as far as regards the generator and the dry-gas chamber, a different gear-connection of the motor and car may be employed.

Having described my invention, what I claim is- 1. A car of the class described, in combination with a motor mounted thereon and with a generator arranged beneath the seats and connected with the motor, substantially as specified.

2. In acar of the class described, andin combination with a motor arranged thereon, a

generator arranged beneath the seats, and a In testimony whereof I affix my signature in presence of two witnesses.

PATRICK J. MOMAHON.
